[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a cable bridge welding device, including a slot-type bridge 1, the slot-type bridge 1 is formed into a slot shape by bending a plate, the outer wall of the slot-type bridge 1 is welded with slot-type docking plates 2 at both ends, the slot-type docking plates 2 can improve the deformation resistance of the two ends of the slot-type bridge 1, the outer peripheral wall of the slot-type docking plate 2 is provided with evenly distributed card grooves 21, preferably, at least two card grooves 21 are provided on the three sides of the slot-type docking plate 2. It also includes a clamping block 3, one side of the clamping block 3 is provided with a V-shaped buckle groove 4 with the large end facing outward, and a positioning shaft 5 with a clearance fit with the card groove 21 is fixedly connected between the two inclined surfaces in the V-shaped buckle groove 4. The function of the positioning shaft 5 is to align the card grooves 21 on the two slot-type docking plates 2 that need to be aligned, and the function of the V-shaped buckle groove 4 is to use its V-shaped groove to clamp the two slot-type docking plates 2.

[0024] Furthermore, evenly distributed anti-skid protrusions 41 are provided on the two inclined surfaces in the V-shaped buckle groove 4. The function of the anti-skid protrusions 41 is to prevent the clamping block 3 from slipping and disengaging when it is knocked to clamp the two groove-shaped docking plates 2.

[0025] A cushioning rubber pad 8 is bonded to the side of the clamping block 3 that is away from the V-shaped buckle groove 4. The cushioning rubber pad 8 is the part struck by the hammer, and the purpose is to reduce the striking noise.

[0026] In this embodiment, the cross-section of the positioning shaft 5 is square, and the width of the slot 21 is greater than or equal to the width of the positioning shaft 5. This setting prevents the positioning shaft 5 from twisting after entering the slot 21, making it easier to guide the V-shaped buckle groove 4 to squeeze the two groove-shaped docking plates 2.

[0027] In this embodiment, one side of the slot-type butt joint plates 2 located at both ends of the slot-type bridge frame 1 is provided with staggered welding holes 22. That is to say, when the two slot-type butt joint plates 2 are aligned, the welding holes 22 on the two are staggered. At this time, the two slot-type butt joint plates 2 can be welded together by filling the welding holes 22 with filler welding, thereby reducing the difficulty of welding.

[0028] In this embodiment, a guide shaft 6 arranged along the length direction is welded to the bottom of the inner bottom of the trough-type bridge 1, and the guide shaft 6 is provided with a pressure rod 7. The middle part of the pressure rod 7 is provided with a connecting hole 71 with a clearance fit with the guide shaft 6. The clearance fit here means that the pressure rod 7 can rotate relative to the guide shaft 6. A pressure plate 9 is screwed on the top of the guide shaft 6. After the pressure rod 7 spans the cable, when the pressure plate 9 is tightened, the pressure rod 7 will squeeze the cable. When the pressure rod 7 is rotated until it is parallel to the cable, the cable can be easily taken out of the trough-type bridge 1.

[0029] Furthermore, a shift plate 91 located on the outer periphery of the connecting hole 71 is welded to the top of the pressing plate 9 . The shift plate 91 is a handheld component for manually shifting the pressing plate 9 to rotate.

[0030] Working principle: When two adjacent sections of trough-type bridge frames 1 need to be butt-welded, move the trough-type butt plates 2 between the two close together, then take a clamping block 3, align the positioning axis 5 on the clamping block 3 with the card slots 21 on the two trough-type butt plates 2, and then use a hammer to knock the buffer rubber pad 8. At this time, the V-shaped buckle groove 4 will squeeze the two trough-type butt plates 2 toward each other. In this way, install the clamping block 3 on the other card slots 21, and finally perform filler welding at the welding hole 22 to complete the welding connection of the trough-type bridge frames 1 at both ends.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
